Abstract :

Sediments transported by water flow, an important factor in the formation of the geometrical structure and morphology of rivers considered. In this paper, the process of sedimentation Karun river was simulated using the Gstars3 software in the range of Ahvaz hydrometric stations to Farsiat a length of about 50 km. The purpose of this study was to select a suitable mathematical model for estimating the sediment transport rate in a way that is able to simulate accurately in the river. Calibration of sedimentary depositional model shows that for the the range the relationship Ackers- White (1973) and (1990) fitted to existing conditions are Karun River. Also sedimentation volume of hydrometric stations in Ahvaz and Farsiat 18.25 and 16.65 million cubic meters per year respectively was estimated. This indicates that the area is strongly depositing.
